WARREN W. HSLETT AND EAMES BLAEER, OF BALTEMORE,`MARYLAND.

minerais rarita: BURNER.

Application filed July 3,

To a-ZZ whom it may concern.'

Be it known that we, WARREN TV. Has- LETT and JAMES BLAIR, the former a citizen ot the United States and the latter a subject of Great Britain, bot-h residing at Baltimore, in the State of Maryland, have invented certain new and useful improvements in Electric Paint Burners, of which the following is a speciication.

This invention relates to improvements in electric paint burners, and has for its object to provide asimple and eflicient portable device for burning painted surfaces, and which is electrically heated to such a degree that when held close to the said surface the paint will be quickly burned or blistered so that it canbe readily scraped therefrom.

The invention consists of the novel construction and arrangement of the parts and combination ot parts hereinafter more fully set forth in the following specification and v pointed out in the appended claims.

In the accompanying drawing,

Figure 1 is a front elevation of our invention.

Figure 2 is a side elevation of Figure 1.

Figure 3 is a section on the line 2 2 of Figure l.

Figure et is a detail rear view of the porcelain insulator which carries the resistance wires and switch.

Referring to the accompanying drawings, forming part of this specification, and in which like reference numerals designate like parts throughout the several views thereof, 1 designates a metal box in which is removably tted a porcelain, or other suitable non-conducting, piece 2 having grooves 3 in the front and one side thereof into which are secured the resistance wiresd and 5, respectively. The said front and side being covered with a piece of mica 6 and 7, respectively, to prevent dirt or the burnt paint from coming into contact with the resistance wires 4 and 5, and is also provided with guards 8 to prevent the mica from being broken and to keep the device -from touching the surface from which the paint is being burned. Within the said box and secured to the inner lower surface of the porcelain piece 2 are contact plates 9 and 10, the one 9 being connected by the wire 11 to the resistance wires 4 at the front of the device and the other 10 being connected by the wire 12 to the resistance wires 5 at the side of the device.

The binding posts and 1- 1 are connected by wires 15 to a suitable source of current supply. The post 14: is connected by a wire 16 to the front .and side resistance wires 4 and 5, and the post 13 is connected to the switch 17 which latter is provided with a blade 18 on its inner end adapted to be thrown into contact with the contact plates 9 and 10. When it is desired to heat from the front of the burner the switch is turned to throw the blade 18 into contact with the plate 9, as shown in Figures 3 and et of the drawing, which carries the current only to the resistance wires i at the front, and when it is desired to heat from the side, the switch is turned to throw the blade 18 in contact with the plate 10 which causes the current to dow only to the wires 5 at the side of the burner. Back of the porcelain piece 2 is a sheet of asbestos 19 to keep the heat from the back of the device, to Whiclrthe handle 20 is secured and by means of which latter the device is operated over the surface from which the paint is being burned.

lt will be seen that by the use of our invention the aint can be quickly burned from any sur ace, and when the device is to be used in narrow places, such as the spaces between window beads, the device can be switched so that it can be used from the narrow side which is adapted to fit into such narrow spaces.

Vihile we have shown and described a porcelain piece to which the resistance wires are secured, it is obvious any other suitable non-conducting material may be employed in lieu thereof.

Having thus described our invention, what we claim is:

1. An electric paint burner comprising a l box, a piece ott non-conducting material secured in said box and extending across two sides thereof, a number of resistance wires Secured to the outer surface of said nonconducting material on said two sides. a .Contact plate ,connected to the resistance wires at one side of said boit. a contact plate connected to the resistance wires at the other side of said box, two binding posts adapted to be connected in circuit with a suitable current supplyI a switch having a blade adapted to be thrown into contact with either of said contact plates to carry the current to the resistance wires at either of said sides.

2. An electric paintQburner, comprising a box, a piece of non-conducting material Within said box extending 'across the front and one side thereof, resistance wires secured to the outer surface of the front of said Conducting` material, resistance wires secured to the outer surface of the side of said non-conducting material, a contact plate connected to the resistance wires at the front of the box, a Contact plate connected with the resistance Wires at the side of the box, two binding posts one of which is connected to the resistance wires at the front of the boX, a switch connected to the other binding post and having a blade IAdapted to be thrown into Contact with either of said contact plates to establish a. circuit to either the 'resistance Wires at the front or the Wires at the side of the box, and Iguides extending across the front and side of the box.

In testimony whereof we afix our signatures.
